There is a loud noise after ANC or Awareness mode is enabled on HUAWEI earbuds

Problem

Problem 1: There is a loud noise when the earbuds are touched

  • When ANC, Awareness, or Clear voices is enabled on the earbuds, holding them in any of the following ways, such as adjusting the volume, pinching the microphone, holding the earbud handle with one hand, or putting the earbuds in a pocket, can cause continuous and sharp loud noises. The noises stop when the user releases the earbuds.
  • When ANC, Awareness, or Clear voices is enabled on the earbuds, lying on one side, pressing the ear tips, holding the earbuds tightly, or pinching the microphone can cause intermittent or continuous loud noises. The noises stop when the user adjusts the earbuds.

Problem 2: There is a loud noise when the earbuds are not touched

After the earbuds are worn, the earbuds emit loud noises even if they are not blocked or touched.

Problem 3: There is a loud noise when the earbuds are placed in the charging case

For FreeBuds SE 4 ANC, if ANC, Awareness, or Clear voices is enabled, the earbuds are placed in the charging case, and the charging case is out of power, a short loud noise may be audible from the earbuds when the charging case is closed.

Problem 4: There is a loud noise when the hearing aid feature is used

When the hearing aid feature is enabled on FreeBuds Pro 5, Awareness is automatically enabled. In this case, covering ears or lying on one side can cause a loud noise.

Cause

Scenario

Cause

When the earbuds are touched
  • When ANC, hearing aid, or Awareness is enabled on the earbuds, the microphone may amplify the sound in an enclosed environment and feed it back to the speaker. This can cause a feedback loop, resulting in loud noises similar to those when you put a microphone next to a speaker.
  • Smudges and dirt have blocked the holes on your earbuds, the earbuds have been damaged due to a fall, or your earbuds have liquid damage, which affects the acoustics of your earbuds and may cause abnormal loud noises.
  • The microphone holes of HUAWEI FreeBuds 6 are located on the rear of the earbuds handles. In this case, when you use the earbuds to adjust the volume, you may touch the microphone holes accidentally and leave dust and other foreign objects on the holes, resulting in loud noises.

When the earbuds are not touched

When hearing aid is used

When placed in the charging case
  • When the charging case of FreeBuds SE 4 ANC earbuds is out of power, it cannot detect whether the earbuds are in the charging case. As a result, ANC or Awareness will remain enabled in an enclosed environment, resulting in a feedback loop and a loud noise.

Solution

If there is a loud noise when the earbuds are touched, performing the following:

  1. When taking or operating the earbuds, avoid covering the microphone of the earbuds, for example, the rear of the FreeBuds 6 earbuds handles.
  2. When holding the earbuds, keep your fingers slightly loose to avoid completely covering the earbuds with your palm. This can help reduce the chance of loud noises caused by an enclosed environment.
  3. Clean the earbuds on a weekly basis to ensure an optimal noise cancellation experience.

If there is a loud noise when the earbuds are not touched, perform the following:

  1. Select a pair of ear tips that best fit your ears and adjust the earbuds to ensure that they fit well in your ear canals.
  2. When taking or operating the earbuds, avoid covering the microphone of the earbuds, for example, the rear of the FreeBuds 6 earbuds handles.
  3. Clean the earbuds on a weekly basis to ensure an optimal noise cancellation experience.
  4. In quiet environments, set ANC to Cozy mode or disable ANC.

If there is a loud noise when the earbuds are placed in the charging case, perform the following:

If the charging case of your FreeBuds SE 4 ANC earbuds is out of power, charge the case. A charged charging case will automatically disable ANC or Awareness to suppress loud noises.

If there is a loud noise when the hearing aid feature is used, perform the following:

When hearing aid and Awareness are enabled on your FreeBuds Pro 5 earbuds, it is recommended that you keep your ear canal unobstructed (such as by hands and pillows) while wearing the earbuds, to avoid loud noises.

If the issue persists, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
